College students are active, sunny, simple, kind and lively. In the era of the rapid development of the Internet, we college students should be on all platforms of the network when surfing the Internet. Although civilized speech says freedom of online speech, we must be brave enough to refute and report some extremely negative and bad speech. We must not let some negative language affect the cyberspace that is difficult to govern, and we must not browse bad websites or forward bad information. Dare to report complaints when encountering bad information. Internet is a public domain, but it is not a place of extra-legality, especially cyber violence. Everyone has his own way of life. Please don't hurt others at will. Good words warm three winters, but bad words hurt people in June. The degree of network civilization is hoped that everyone can experience it. We college students are the next generation successors and new impetus of society, and we have the obligation and responsibility to create a harmonious and fresh cyberspace.
